To all whom it may concern: I I,

Be it known that I, ELMER E. PALMER, of

Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Urinals, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in urinals of the open stall type adapted to be used in public buildings, depots and other places where such fixtures or apparatus may be convenient. The diffi culty in maintaining these public urinals and environments in a perfectly sanitary and odorless condition is universally recognized and in most instances this is attributable to imperfect drainage, improper ventilation or to the use of unsuitable material and loose manner of assembling the with as few joints as possible, and byproviding the stalls with lower and upper ventilating ports which communicate by indirect passage with a main ventilating flue.

Another object of equal importance is to locate the flush pipe in a horizontal plane between the lower and upper ports so as to constantly discharge the water downwardly against the back or impact plates which in turn conduct the excretion and water to an underlying inclined trough, the latter communicating at its low point with a suitable sewer pipe.

The displacement of air by the continuous downward discharge of water from the flush pipe naturally causes a rush of air against the back plates, part of which air is carried downwardly by the water current and escapes to the ventilating flue through the lower ventilating ports but the greater part of such air is brought into a whirl or eddy moving against the back plates and unless some provision is made for the breaking up or disintegration of this eddy, the same air will continue its whirling motion in sub stantially the same place and soon become vitiated thereby renderin the air with which it comes in contact foul and odorous and cause the entire air throughout the room to become foul odors.

The object, therefore, in providing ventilating ports above and beneath the flush pipe or rather in locating the flush pipe between the lower and upper ventilating ports and connecting said ports to the main ventilating flue in which a continuous updraft is maintained, is to break up or disintegrate the eddying currents of air which may tend to accumulate in proximity to the back or impact plate.

ther objects and uses relating to specific parts of the system will be brought out in the following description.

In the drawingsFigure l is a perspective View of a multiple urinal system embodying the various features of my invention but omitting the main ventilating flue.

permeated with the same Fig. 2 is a transverse sectional view through the apparatus seen in Fig. 1. Fig. 3 is a longitudinal vertical sectional view through the several stalls and underlying slab in which the drain trough is formed.

In carrying out the objects stated I first construct a suitable foundation l of masonry of any approved construction and of SHfiTClGlll? length to receive and support a continuous superposed slab -2 of slate or equivalent non-absorbent material having its upper face provided with a lengthwise channel ,.3' terminating near the ends of the slab and having its bottom inclined from one end to the other, said channel communieating at its low end with a suitable soil pipe -4-, the latter being adapted to be connected to a sewer or other drainage conduit, not shown. This slab is usually'coextensive in length with that of the combined stalls presently described and upon the front edge of the slab 2 at the front side of the trough 3 is placed a series of spacing blocks 5 also of slate which are spaced a uniform distance apart corresponding to and directly under the partitions or sides of the stalls and serve to support the rear edge of a superposed slab 6 of slate, this latter slab being continuous from end to end and of a length substantially coextensive with that of the combined stalls, said slab 6- being of considerably greater width than the underlying slab 2 and has its front edge projecting across a ventilating space 7 as best seen in Fig. 2 and supported upon the upper edge of a suitable foundation "8 and in this particular instance is embedded in a concrete floor -9 forming the top of the foundation 8. The ventilating space 7 is, therefore, inclosed by the foundations -1 and -8 and coping 6, the rear foundation 1 being provided with a ventilating passage l0 which connects the ventilating space 7 with a main ventilating flue The spacing blocks 5 serve the purpose of supporting the rear edge of the coping 01' floor slab -6 some distance above the upper face of the trough slab -2 leaving intervening ventilating spaces -12 between the spacing blocks and also between the trough slab -2 and floor slab 6, which connect the ventilating spaces -7 with the lower portions of the stalls hereinafter described.

The floor slab -6 is made in one piece and laid on a slight incline transversely from front to rear with its rear edge eX- tending a short distance beyond the spacing blocks -5and front edge of the trough slab --2 and terminates directly over the trough or chamber 3 so any accumulations of moisture upon the upper surface of the floor slab 6 will readily flow rearwardly and downwardly from the rear edge of the slab 6 into the underlying trough -3 where such moisture will readily flow along the inclined bottom 3 into the soil pipe 4.

The urinal proper consists in this instance of a series of stalls each comprising back plates -l3 and sides -l4t-, which are capped by a suitable coping or top plate 15 all of which latter parts are made of slate.

The back piece 13 which may be made in a continuous slab of slate is disposed in a vertically inclined plane with its lower edge seated in a groove -16-- upon the upper face of the trough slab 1- which is at the rear of the trough 3 where it is cemented or otherwise secured in place, the upper edge of said back piece abutting against and secured to the under side of the top plate -15 and is provided with a series of ventilating ports 18 one for each stall, said ventilating ports 1S being formed by cutting away portions of the upper edge of the plates 13 between the side pieces 14t.

The intermediate side pieces 14 are disposed in parallel vertical planes uniform distances apart with their lower edges resting upon and secured to the upper face of the floor plate -6 directly over and in vertical alinement with the spacing blocks 5 while the side pieces at the ends are similarly disposed but have their lower edges resting upon the upper faces of the end spacing blocks 5 between the end of the floor plate 6 and outside concrete lloor -9, the upper edges of said pieces all terminating against the under side of the top plate 15.

The rear edges of the side pieces -l-:lfollow the upward incline of and are secured to the back piece 13 against which they abut while the front edges are preferably disposed in vertical, planes so that each side piece 14 extends forwardly from the back piece over and in front of the underlying groove or channel 3 and are of suflicient transverse width from front to rear to practically conceal the occupant of the stall.

The lower rear edges of the intermediate partitions or side pieces 14: are cut away forming ventilating ports 19 connect ing the seveal stalls and communicating with the trough -3 through suitable passages 20 which are formed between the rear edge of the floor slab (3 and front face of the adjacent portion of the back piece 13 and which latter cause the excretions and water to flow downward from the back piece l3 into the trough 3 and also allows the vitiated. air to escape through the ventilating spaces 12 into the chamber 7 and thence through the passage -10 into the main ventilating flue --11-.

It is now clear that each stall is provided at its lower side with ventilating ports 19 and 20 for ren'ioving the (lownwardly flowing currents of air, while the upper portion of the stall is similarly provided with a ventilating port 1S for permitting the escape of the upwardly flowing vitiated air or gases thereby taking care of all foul air and gases which may tend to accumulate in. the stall.

In order that the back piece -l3- which constitutes the impact plate of each stall may be thoroughly and continually cleansed from excretions, I provide a tlush pipe -21 which is common to all of the stalls and is located in a horizontalplane between the lower ports *19* and upper ports 18 and directly in front of the back plate 13, said flush pipe being provided in its lower side with line apertures -2- through which jets of water are discharged continuously and downwardly against the front faces of the back impact plates of each stall striking said back plate which is above the point where the excretions are more liable to accumulate thereby keeping the impact plates entirely free from such accumulations and depositing the same into the underlying trough 3 where they are immediately carried away to the soil pipe 4.

The back piece 13 constituting the impact plates of the several stalls is located some distance in front of the adjacent side of the main ventilating flue 11- leaving an intervening space -25- extending from the top plate -15- downwardly at the rear of the trough slab l and communicating 'at its lower end with the passage -10- and main flue l1, the lower end ofthe short side of said main flue being provided with a passage -26 connecting the lower end of the ventilating space 12 with the interior of said flue.

The top plate 15 which rests upon the upper edges of the back piece -13 and Side pieces 14l-- extends some distance forwardly and upwardly beyond the back piece -13 and its rear edge is preferably embedded in the adjacent wall of the main fine 11 so as to firmly hold it in place. and form a substantially air tight joint with the flue as well as with the upper edges of the back and sides of thestalls.

The main water supply pipe as 27 which supplies water to the flush pipe2l-- preferably extends downwardly through an aperture in the top plate 15 close to the front wall of the flue l1 and into the upper portion of the space -25 where it is offset laterally through an aperture in the back 13- and connected to the flush pipe -2l, said supply pipe being provided with a suitable valve 28 to regulate the discharge of water from said flush pipe.

It is desirable to provide some means for creating an up-draft of air through the ventilating flue 11 and for this purpose I have located in the lower portion of the fine a suitable heater 28 which reduces the specific gravity of the air and causes it to rise more or less rapidly through the flue thereby drawing the vitiated air from the chamber and ventilating spaces -25 to which such vitiated air readily escapes from the room in which the stalls are located through the lower ports 19- and 20 and upper ports 18-.

The downward discharge of water from the flush pipe against the impact plates causes more or less down draft of the vitiated air in the immediate vicinity of the stalls, said vitiated air finding exit through the ports 19- and 20 and 12- to the chamber 7 and thence to the ventilating lines through the passages 10 and 26 but this action of the water tends to produce a circular motion of the air some distance above the bottom within the center of the whirl or eddy in the vicinity of the discharging water so that unless some provision is made for breaking up or disintegrating these eddying currents they will continue to revolve or whirl in the upper portions of the stalls and soon render the whole atmosphere of the room more or less foul, and in order to overcome this, I have provided ventilating ports -18 which are above the flush pipe -21 in line with the backwardly moving currents of air so that the air which rushes rearward'ly against the back plates finds ready exit through the ports -18 thus breaking up or disintegrating the tendency toward eddying currents and causing the vitiated air in the upper portions of the stalls to readily escape through the ports l8 and into the ventilating space 25-- and thence into the ventilating flue 1- which extends some distance to the exterior of the building.

It will be seen from the foregoing description that the principal features of my invention are :1st the construction and relative arrangement of the trough and floor slabs together with the intervening spacing blocks and ventilating ports, and 2nd, the relative arrangement of the flushing pipe between the lower and upper ventilating ports of the several stalls whereby a part of the foul air is carried off through the bottom ports and aided by the down rush of water while the tendency of the air to form into eddys or whirls in the upper part of the stall is obviated by the upper ports which operate to split up or disintegrate these eddying currents of air which are more or less vitiated and to convey such vitiated air from the upper portions of the stall to the main ventilating fine, the lower and upper ventilating passage of the several stalls communicating by indirect passages with a single opening in the front side of the main ventilating fine and by heating the air in said flue it is clearly evident that a strong upward draft therein is continually maintained tending to augment the withdrawal of foul air or gases from the stalls into said flue.

What I claim is:

1. In a urinal system, the combination of a slab having a lengthwise trough in its upper side, the bottom of which trough is inclined from one end toward its opposite end, a discharge pipe communicating with the low end of said trough, a series of spacing blocks mounted upon the upper edge of said slab at one side of the trough and spaced some distance apart forming intervening ventilating passages, a floor slab having one edge resting upon'the upper faces of said spacing blocks and inclined transversely toward the underlying trough slab, the rear edge of said floor slab terminating directly over the trough, a support. for the floor slab and forming in connection with the trough and floor slabs a ventilating space with which said passages communicate, a back piece having its lower edge resting upon the upper face of the trough slab at the rear side of the trough, and side pieces having their lower ends resting upon theupper face of the floor slab directly over said spacing blocks and their rear edges secured to the back piece leaving an intervening ventilating'passage between the back piece and rear edge of the floor slab, a flushing pipe discharging against'the back piece, said back piece having ventilating ports above the flush pipe to break up and carry 01F eddying, currents of air which may tend to accumulate in the vicinity of the flush pipe.

2. A urinal system comprising a slate slab having a lengthwise trough in its upper side, the bot-tom of said trough inclining lengthwise from one end toward the passage end, a discharge pipe communicating with the low end of said trough, a series of spacing blocks of the same material seated upon the upper face of the trough slab and spaced some distance apart to provide ventilating spaces, a floor slab *of slate having its rear edge resting upon the upper faces of said spacing blocks and terminating directly over said trough, a support for the floor slab and forming in connection with the trough and floor slabs a ventilating space with which said ventilating passage is communicated,

an upwardly and rearwardly inclined back piece having, its lower end resting upon the upper side of the trough slab at the rear of said trough some distance from the rear edge of the floor slab leaving an intervening ventilating space communicating with the spaces between said blocks, upright side pieces having their lower edges resting upon the top face of the floor slab and provided with ventilating ports communicating with the ventilating spaces between the floor slab and back piece said back piece having, its upper edge provided with a ventilating port, a main ventilating flue communicating with said ventilating ports, and a flush pipe located in the horizontal plane between the upper and lower ventilating ports.

In witness whereof I have hereunto set my hand this 22 day of January 1908.
